[アーティクル]
07/13/2016

Tests to determine whether a moniker supports asynchronous binding.

Syntax

HRESULT IsAsyncMoniker(
  _In_ IMoniker *pmk
);

Parameters

pmk [in]
The address of the IMoniker interface of the moniker to test.

Return value

Returns one of the following values.

Return code	Description
E_INVALIDARG	The pmk parameter is invalid.
S_FALSE	The specified moniker is not asynchronous.
S_OK	The specified moniker is asynchronous.

Remarks

A moniker implementation is asynchronous if it supports the IAsyncMoniker interface, which is an empty interface that is an implementation of IUnknown. The IsAsyncMoniker function tests for support of IAsyncMoniker and handles composite monikers correctly.

No public headers define the IAsyncMoniker interface; however, you can support the interface by returning a pointer to your object in response to QueryInterface for IID_IAsyncMoniker, which is defined as follows:

DEFINE_GUID(IID_IAsyncMoniker, 0x79eac9d3,0xbaf9,0x11ce,0x8c,0x82,0x00,0xaa,0x00,0x4b,0xa9,0x0b);

Requirements

Minimum supported client	Windows XP
Minimum supported server	Windows 2000 Server
Product	Internet Explorer 3.0
Header	Urlmon.h
Library	Urlmon.lib
DLL	Urlmon.dll
